Project description

We are undertaking a project to strengthen and replace various components of the Bascule Bridge. As part of this project, the following elements will be addressed:

“Trunnion” is a French word for “pivot point.” A trunnion describes the type of bridge that pivots like a see-saw around a central core. This is a key operational component of the bridge that requires regular scheduled overhauls to ensure ongoing unimpeded operations.

Bascule bridges are fitted with counterweights. These offset the weight of the span, which facilitates the raising and lowering of the bridge. Inspections of the counterweight system indicate that repairs and renovations are required to maintain ongoing health and safety standards for pedestrians, and public and commercial traffic on the bridge.

This project will extend the service life of each of the components by another 30 years. It will improve the condition and operation of the Bascule Bridge, and ensure the safety of bridge users.

Bridge closures

Construction is scheduled for the traditional off-seasons, from November 2023 to the end of April 2024, and from November 2024 to the end of April 2025. Limited bridge closures will be essential to complete the required construction work.

During construction, the following traffic adjustments are expected:

Public notices about the closures will be issued in advance and shared through our social media channels. This will ensure that the public is aware of each closure and its impact on local traffic. The same information will be distributed to stakeholders for further broadcasting.

Key milestones

Project background

In early 2021, the project team started work on plans to rehabilitate the Bascule Bridge. While planning for this project, the project team contacted and consulted with various stakeholders who would be directly affected by the project:


On Wednesday, October 25, we hosted a virtual public information session. This session provided an overview of the project, the project schedule, and completion plans. Information about any future sessions will be shared on this web page and on our social media channels.
